Question

solve the equation by completing the square

m^2+7m-294=0

Answer 1

hello can you help?

Answer 2

by adding and subtracting the square of the half factor of (m)
7/2 = 3.5
(3.5)^2 = 12.25

Answer 3

ya i got that but then i got confused after doing
m^2+7+12.25=294+12.25

Answer 4

im not understanding this thanks soo much for coming back

Answer 5

(m+3.5)^2 = 306.25
so \[\sqrt{(m+3.5)^{2}} = \sqrt{306.25}\]
then m+3.5 = 17.5
so m = 14 ;)
